“If current climate models from the IPCC included data from ice dynamics in Greenland, the sea level rise estimated during this century could be twice as high as what they are currently projecting,” she [Beata Csatho] said.

I suggest that they somehow extrapolate their results also to other outlet glaciers in Greenland, though this may not be quite appropriate or over selling in your term 😉

Despite the overwhelming evidence to the contrary I can prove I’m not just blatting about this since I did read the paper (free copy here). I just don’t remember whether it said anything specific about the other outlet glaciers. That the IPCC was guessing is uncontroversial. 🙂

Back on-topic, I just looked briefly at Citizendium, the alleged fix for the alleged problem, and I’m unimpressed.

I think non-experts can spot and fix errors – I’ve done it often enough on wikipedia, including articles and topics I don’t normally edit (e.g., an article on a movie I just saw). I won’t be as good at it as an expert, but there’s a lot more of us non-experts.
